Adrien Grand commented on LUCENE-10544:
---------------------------------------
I don't think there is any issue with custom bulk scorers, you could delegate
to any bulk scorer? I'm thinking of doing something like this:
{code}
@Override
public int score(LeafCollector collector, Bits acceptDocs, int min, int
max) throws IOException {
int interval = 4096; // TODO: tune me
while (min < max) {
// TODO: check timeout here
final int newMax = (int) Math.min((long) min + interval, max);
min = in.score(collector, acceptDocs, min, newMax); // in is the
wrapped bulk scorer
}
return min;
}
{code}
> Should ExitableTermsEnum wrap postings and impacts?

> URL: https://issues.apache.org/jira/browse/LUCENE-10544
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/index
> Reporter: Greg Miller
> Priority: Major
>
> While looking into options for LUCENE-10151, I noticed that
> {{ExitableDirectoryReader}} doesn't actually do any timeout checking once you
> start iterating postings/impacts. It *does* create a {{ExitableTermsEnum}}
> wrapper when loading a {{{}TermsEnum{}}}, but that wrapper doesn't do
> anything to wrap postings or impacts. So timeouts will be enforced when
> moving to the "next" term, but not when iterating the postings/impacts
> associated with a term.
> I think we ought to wrap the postings/impacts as well with some form of
> timeout checking so timeouts can be enforced on long-running queries. I'm not
> sure why this wasn't done originally (back in 2014), but it was questioned
> back in 2020 on the original Jira SOLR-5986. Does anyone know of a good
> reason why we shouldn't enforce timeouts in this way?
> Related, we may also want to wrap things like {{seekExact}} and {{seekCeil}}
> given that only {{next}} is being wrapped currently.
